CHlCKEN-BROODER.

SPECIFICATION forming part of Letters Patent N0. 644,599, dated March 6,1900.

Application filed November 2, 1899. Serial No. 735,612. (No model.)

T0 at whom it may concern.-

Be it known that I, ERNEST FRANKLIN HODGSON, a citizen of the UnitedStates, residing at Dover, State of Massachusetts, have invented certainnew and useful Improvements in Chicken-Brooders, of which the followingis-a specification.

My invention relates to a chicken-brooder and its object is to preventundue heating of the parts of the burner, while at the same timeutilizing the heat, so as to render it unnecessary to waste the heat inorder to properly ventilate and cool the parts of the burner or heater.In brooders as now constructed, in which lamp-stoves are used as theheating means, the heat is communicated from the wick-tube and chimneyto the oil tank or reservoir, which becomes hot, with its contents, andthis causes an overheating of the brooder, which requires so muchventilation as to be wasteful of the heat and to make it difficult tomaintain an even temperature. I aim to obviate this difliculty by myinvention, and I do it in a very simple manner-namely, by theinterposition of a diaphragm between the upper end of the wick-tube andthe oil-tank and by exposing the oil-tank on all sides to theatmosphere, so that it is kept cool and prevented from overheating.

In the accompanying drawings I have ill ustrated my invention, showing,in Figure 1, a sectional view with the oil-tank and chimney in sideelevation. Fig. 2 is a perspective view of the invention. Fig. 3 shows afront view of a brooder with my attachment in place.

In carrying out my invention I use a plate of sheet metal A, having aturned-up front end B, forming the front wall of the lampchamber. Aboveand resting upon this plate is the chimney O of a lamp-stove, whilebeneath the position of the plate A is an oiltank D, having a wick-tubewhich extends up through an opening in the plate A directly beneath thechimney. Thus the plate A serves as an interposed diaphragm between theoiltank and'the flame and protects and shields it from the heat, theoil-tank occupying the space beneath the plate A, which is open to thefront and exposed to the outside air, and this also tends to keep itcool, as the air passing from the front to the openings in rear of thelamp-body is caused to flow over and around the said lamp-body, whenceit flows up through the openings and in an opposite direction above theplate, escaping by openings in the upturned end B. The oil-tank has afilling-tube 1) extending to the front, so that it may be filled easily.The wickraising spindle is also extended to the front, as shown at c.The plate A fits in guides in the sides of the brooder-opening, as shownat d, and the whole attachment may be drawn out whenever required.

It is not always necessary to use a chimney, and, as shown in Fig. 2, insuch cases the end of the burner projects above the diaphragm, so as tosupply the heat to the lamp-chamber, while the oil-tank is beneath thediaphragm surrounded by the outside air.

What I claim is-- 1. In a chicken-brooder, the combination with the bodyportion having a broodingchamber, and an open space centrally beneaththe same, of a plate located in said space and forming an elongatedheating-chamber said plate having an upwardly-extending front,

and a lamp-body carried below said plate and.

plate and in the opposite direction above, substantially as described.

-2. In a chicken-brooder, the combination with the body portion having abroodingchamber and having a centrally-open space, of a plate slidablylocated in said space and having an upwardly-turned front provided withperforations, a lamp-bod y located below said plate and having a burnerlocated above the same, and openings in said plate in rear of said lamp,substantially as described.

3. In combination with the plate A, a chimney secured thereto, anoil-tank beneath the same and an elongated filling-tube extending fromthe oil-tank to the front and an elongated wick-raiser stem extendingfrom the wick-tube to the front, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
